to have an unconstrained anonymous array with an initial value.

Initialize the new Access_Definition field in N_Object_Renaming_Decl

2004-02-02 Jose Ruiz <ruiz@act-europe.fr>
* restrict.adb: Use the new restriction identifier
No_Requeue_Statements instead of the old No_Requeue for defining the
restricted profile.
* sem_ch9.adb (Analyze_Requeue): Check the new restriction
No_Requeue_Statements.
* s-rident.ads: Adding restriction No_Requeue_Statements (AI-00249)
that supersedes the GNAT specific restriction No_Requeue. The later is
kept for backward compatibility.
2004-02-02 Ed Schonberg <schonberg@gnat.com>
* lib.ads, i-cobol.ads, * s-stoele.ads, s-thread.ads, style.ads,
5staprop.adb, atree.adb, atree.ads, g-crc32.ads: Remove redundant

annotating types.
2004-02-02 Olivier Hainque <hainque@act-europe.fr>
* init.c (__gnat_install_handler): Setup an alternate stack for signal
handlers in the environment thread. This allows proper propagation of
an exception on stack overflows in this thread even when the builtin
ABI stack-checking scheme is used without support for a stack reserve
region.
* utils.c (create_field_decl): Augment the head comment about bitfield
creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
here, because the former is not accurate enough at this point.
Let finish_record_type decide instead.
Don't make a bitfield if the field is to be addressable.
Always set a size for the field if the record is packed, to ensure the
checks for bitfield creation are triggered.
(finish_record_type): During last pass over the fields, clear
DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P
from DECL_BIT_FIELD.
